Magnetism
When two magnets push away from one another; happens when two north or two south poles meet.
What is repelling?
This flows from high to low voltage.
What is electric charge?
A buildup of electric charge on an object or surface.
The loop (path) along which an electric current travels.
What is an electric circuit?
A temporary magnet that works only when electricity runs through it.
What is an electromagnet?
When two magnets draw toward one another; happens when a north and south pole meet.
What is attraction?
Electric charge always flows from...
What is negative to positive?
An electric circuit with no breaks.
What is a closed circuit?
An electric circuit with a break in it.
What is an open circuit?
A machine that uses a magnet to change mechanical energy into electrical energy.
What is a generator?
An invisible area where magnetic forces are present.
What is a magnetic field?
These are ways to keep a house from overheating.
What are fuses and circuit breakers?
Materials that allow electric current to flow through easily.
What are conductors?
Materials that do not carry electric current easily.
What are insulators?
This will decrease the strength of a magnetic field around a wire.
What is use less loops around the iron core?
Two metals that are attracted to magnets.
What are iron and nickel?
These are two differences of parallel and series circuits.
What is 1 path vs multiple paths and all must work at the same time vs things can work independently?
What anything with an electric charge has surrounding it.
What is an electric field?
This contains metal that will melt if it gets too hot to open a circuit.
What is a fuse?
The voltage in a circuit with a current of 6 amps and a resistance of 5 ohms.
What is 30 volts?
Non-magnetic materials become attracted to magnets.
What is Ferromagnetism?
This can increase the resistance of a wire.
What is increasing the temperature of the wire?
The two locations on a battery that must have a path to one another to create an electric circuit.
What are the positive and negative terminals?
This is an example of a parallel circuit.
What is a classroom or house?
A device that detects electric charge.
What is an electroscope?
